Description

Technical Field

[0001] The utility model relates to the technical field of wire processing and detection devices, in particular to a broken wire detection device. Background Art

[0002] The formed wire raw materials after drawing may have internal defects such as shrinkage cavities, porosity, and air bubbles. These defects cannot be detected through appearance. Since wires are widely used in heavy machinery such as cranes, hoists, cable cars, and elevators, if the above-mentioned defects occur inside the wire and are not detected, there will be great potential safety hazards during use. Therefore, the broken wire detection after wire drawing is particularly important. The existing broken wire detection methods usually install a wire flaw detector at the outlet end of the drawing equipment and detect internal defects through the principle of magnetic flux leakage testing. There are also other detection methods such as installing electronic detection equipment.

[0003] For example, the patent document with the publication number CN211446378U discloses a broken wire detection device during wire rope stranding. It is provided with a nylon block; the nylon block is arranged between the post-deformer and the traction wheel group; a strong magnet is arranged at the bottom of the nylon block, and a copper sheet is also installed on the nylon block; the copper sheet is bent upward by 90°, and a long groove is opened on the vertical surface of the copper sheet; the copper sheet is connected to the stop switch circuit of the operation cabinet through a wire. When a broken wire occurs during wire rope stranding, the copper sheet can contact the warped end of the broken wire, and the vehicle platform stop circuit is connected to automatically stop the vehicle.

[0004] For example, the patent document with the publication number CN102384938A discloses a wire rope broken wire detector, which is composed of a U-shaped magnet, a Hall sensor group, a wire rope to be detected, a detection circuit, and an alarm circuit; the Hall sensor group forms a ring, and the wire rope to be detected passes through the central hole of the Hall sensor group. The U-shaped magnet and a small section of the wire rope to be detected form a "mouth" shape, so that the Hall sensor group is located between the N pole and the S pole of the U-shaped magnet, and the wire rope to be detected can move freely left and right. If some wires are broken, when the crack passes through the Hall sensor group, the Hall sensor group detects a large amount of magnetic flux leakage, and after passing through the detection circuit, the alarm circuit emits light and beeps.

[0005] However, the above-mentioned existing broken wire detection devices have the following problems: The wire drawing speed is fast, and the detection reaction sensitivity of the set detection device will decrease, and it is easy to miss detection and misdetection; the requirements for sensors are relatively high, and the sensors need to be frequently detected and replaced, resulting in high costs.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] The utility model provides a broken wire detection device, which includes a bracket, a horizontal detection mechanism and a vertical detection mechanism. The horizontal detection mechanism and the vertical detection mechanism are fixed on the back plate 2 of the bracket, and the horizontal detection mechanism and the vertical detection mechanism are connected through a connecting block 18. Through the arrangement of the horizontal and vertical detection mechanisms, the tension acting on the steel wire is generated in different directions, so that the defective steel wire breaks under the action of the tension in different directions, thereby detecting the defective steel wire.

[0026] In this embodiment, the vertical detection mechanism includes a vertical plate 1 and a vertical wire passing wheel group. The vertical wire passing wheel group is perpendicular to the vertical plate 1 and is installed at equal intervals in the horizontal direction, defining the components of the vertical detection mechanism and determining the installation method of the vertical wire passing wheel group on the vertical plate.

[0027] In this embodiment, the vertical wire passing wheel group includes a wire passing wheel A 5, a wire passing wheel B 6, a wire passing wheel C 7 and a wire passing wheel D 8. The wire passing wheel A 5 and the wire passing wheel C 7 are fixedly installed on the vertical plate, and the wire passing wheel B 6 and the wire passing wheel D 8 are installed on the vertical plate with adjustable height. Further flexibly set the installation method of each wire passing wheel in the vertical wire passing wheel group, so that the gap between the wire passing wheels is adjustable.

[0028] In this embodiment, the wire passing wheel D 8 is installed on the upper right of the vertical plate through an adjusting screw rod B14. The right edge of the mating nut of the adjusting screw rod B14 is aligned with the right edge of the vertical plate 1. The wire passing wheel B 6 is installed on the lower left of the vertical plate 1 through an adjusting screw rod A13. The right edge of the mating nut of the adjusting screw rod A13 is aligned with the vertical center line of the vertical plate 1. The installation heights of the wire passing wheel A 5 and the wire passing wheel C 7 are flush with the depth of the installation hole of the adjusting screw rod A13. Further define the installation positions and methods of the wire passing wheels in the vertical wire passing wheel group, as well as the adjustable range and adjustable direction of the gap between each wire passing wheel, so as to achieve the purpose of detection by the vertical detection mechanism.

[0029] In this embodiment, the horizontal detection mechanism includes a cross plate 3 and a horizontal wire passing wheel group. The horizontal wire passing wheel group is perpendicular to the cross plate 3 and is installed at equal intervals in the horizontal direction, defining the components of the horizontal detection mechanism and determining the installation method of the horizontal wire passing wheel group on the cross plate.

[0030] In this embodiment, the horizontal wire passing wheel group includes a wire passing wheel E 9, a wire passing wheel F 10, a wire passing wheel G 11 and a wire passing wheel H 12. The wire passing wheel E 9 and the wire passing wheel G 11 are fixedly installed on the cross plate 3, and the wire passing wheel F 10 and the wire passing wheel H 12 are installed on the cross plate 3 with adjustable height. Further flexibly set the installation method of each wire passing wheel in the horizontal wire passing wheel group, so that the gap between the wire passing wheels is adjustable.

[0031] In this embodiment, the wire guiding pulley H12 is installed at the upper right of the cross plate (3) through the adjusting screw rod D16. The right edge of the mating nut of the adjusting screw rod D16 is aligned with the right edge of the cross plate 3. The wire guiding pulley F10 is installed at the lower left of the cross plate 3 through the adjusting screw rod C15. The distance from the adjusting screw rod C15 to the right edge of the cross plate 3 is the same as the distance from the adjusting screw rod A13 to the right edge of the vertical plate 1. The installation heights of the wire guiding pulleys E 9 and G11 are flush with the depth of the installation holes of the adjusting screw rod C15, further defining the installation positions and methods of the wire guiding pulleys in the horizontal detection mechanism, as well as the adjustable range and adjustable directions of the gaps between the wire guiding pulleys, so as to achieve the purpose of detection by the horizontal detection mechanism.

[0032] In this embodiment, the bracket includes a back plate 2, a bottom plate 4, a support plate A19 and a support plate B 20. The support plates A19 and B 20 are triangular prisms. The long right-angled sides of the support plates A19 and B 20 are fixed on the back plate 2, and the short right-angled sides of the support plates A19 and B 20 are fixed on the bottom plate 4. There are 2 bolts 17 arranged on the bottom plates on both sides of the support plate A19. The 2 bolts 17 on the same side are aligned in the vertical direction and parallel to the short right-angled side of the support plate A19 in the horizontal direction. By providing the support plates A19 and B 20, the stability of the bracket is enhanced. Bolts are provided on the bottom plate, so that the detection device can be installed at the finished machine end of the wire drawing machine or the wire outlet of other equipment with the need for broken wire detection, and the application range is relatively wide.

[0033] In this embodiment, the connecting block 18 is L-shaped. One side of the connecting block 18 is fixed on the right side edge of the vertical plate 1, and the other side is fixed on the upper side edge of the cross plate 3. By adopting the connecting block 18 with this structure, the horizontal detection mechanism and the vertical detection mechanism can be connected together more firmly.

[0034] During operation, the steel wire enters from the upper tangent line of the wire guiding pulley A 5 of the vertical detection mechanism, winds through the lower tangent line of the wire guiding pulley B 6 in a U shape, and then exits from the upper tangent line of the wire guiding pulley C 7. Through the adjustment of the lower tangent line of the wire guiding pulley D 8, the entry and exit are on the same horizontal line. At the same time, the steel wire enters the horizontal detection mechanism at the same horizontal position and then passes through the four wire guiding pulleys of the vertical detection mechanism in the same way as the vertical detection mechanism. When the steel wire passes through the conversion position between the vertical detection mechanism and the horizontal detection mechanism, if there are defects inside, it will be twisted off by the horizontal and vertical tension forces, and the normal steel wire will pass through smoothly, achieving the detection purpose.

[0035] The method for detecting broken wires in this embodiment is as follows:

[0036] First, fix the broken wire detection device at the finished machine end of the wire drawing machine;

[0037] Then, the steel wire enters through the wire passing wheel A 5 of the vertical detection mechanism and passes through the vertical detection mechanism and the horizontal detection mechanism in a U-shaped winding manner in sequence;

[0038] Subsequently, the gaps between the wire passing wheels are adjusted by using the adjusting screw rod A 13, the adjusting screw rod B 14, the adjusting screw rod C 15 and the adjusting screw rod D 16 to make the steel wire in a taut state;

[0039] Secondly, it is pulled out from the wire passing wheel H 12 of the horizontal detection mechanism, and the inlet and outlet directions of the steel wire are on a horizontal line;

[0040] Finally, when the steel wire passes through the conversion point of the vertical detection mechanism and the horizontal detection mechanism, tensile forces in different directions will act on the steel wire. The steel wire with internal defects such as shrinkage cavities, porosity or bubbles will be broken, and the steel wire without internal defects such as shrinkage cavities, porosity or bubbles will pass through normally.

[0041] The above detection device does not require power drive, relies on a pure mechanical structure, and uses horizontal and vertical tensile forces to achieve the detection purpose. It has high detection efficiency, timely detection reaction effect, convenient operation, low manufacturing and use costs, and a wide range of applications.

[0042] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention under the concept of the present invention, or direct / indirect application in other related technical fields shall be included in the patent protection scope of the present invention.
